Data is the lifeblood of the world ’ s future smart cities . But as connected devices increase , so too will security threats

By 2050 , two-thirds of people globally are expected to live in cities . As urbanisation continues to rise , cities are facing new challenges that require innovative solutions . At the heart of one of these possible solutions , the smart city , is the smart sensor . Distributed in the tens of thousands across smart city test neighbourhoods , or even entire boroughs , IoT sensors monitor everything from traffic patterns and footfall to utility usage and emissions .

One such example of this is the city of Barcelona . The Spanish capital ’ s smart city pilot demonstrates how the smart application of data can transform everything from shopping to transportation , enabling services from autonomous driving to augmented reality .

But as the number of connected devices increase , so too will security threats .

The use of both AI and ML in smart city systems will improve the efficiency of systems and expand their advantages . However , this will also create new avenues for attack through the cloud , as well as make the detection of malfunction behaviours more difficult .
